The stuff form Knight was a light orange color and it did turn green. It was a good cleaner, better than Bonzai and much cheaper. I will call Cardinal and see what they might have. I like the Cardi Blast, but it is more expensive. They also have a good polish that I use.
I have never used the flake, just the beads. They do have an attraction to water/moisture, but I keep the plastic bag wrapped & moisture is not a real problem.
Larry, I usually buy a 500 # drum and get a year out of it. How much do you use when washing vehicles and houses? You're in Salem?
